Cubs will learn about binary code

Beads (at least 3 colours)

Gut/beading string

Binary code chart

Computers assign a string of 0s and 1s to different letters, symbols, and instructions, and this is called binary code. Each Cub is given a list of all the letters of the alphabet, and then pick one color of bead to represent 1 and another color to represent 0. The third colour beads are spaces (or delimiters) between the letters of their name.   Of course, you don’t actually need a delimiter to know when one character ends and another begins in ASCII (assuming you know the start of the whole message), because the size of each character doesn’t vary–we can always rely on each character using exactly 8 bits.

Using the template, Cubs need to write their names in binary code and then, using this as a guide, create their necklaces.
